The utility model discloses a multifunctional food slicing and shredding all-in-one machine which comprises a supporting table, and a connecting groove is formed in the surface of the top of the supporting table. According to the food processing device, food to be processed is placed in the placing cylinder, the motor on the side face of the supporting plate is started to drive the screw rod to rotate, and the moving block is limited and guided through the connecting rod, so that the moving block moves in the axial direction of the screw rod; the moving block synchronously drives the connecting block to slide along the connecting groove in the top of the supporting table, so that accurate displacement of the containing barrel is achieved, when food in the containing barrel moves to the position below the cutter, the reciprocating air cylinder is started to drive the cutter to do vertical reciprocating motion, and slicing or shredding processing of the food is completed. The food positioning problem is effectively solved through the structural design of the containing barrel, the displacement and deflection phenomena in the cutting process are remarkably restrained through circumferential constraint on food, the stability of the relative position of a cutter and the food is ensured, the slicing and shredding uniformity is improved, and the machining precision and the finished product quality are remarkably improved.

This utility model relates to the field of road engineering technology and discloses a frost heave and differential settlement control structure suitable for culvert sections in cold regions. The structure, from top to bottom, includes a roadbed, a fill matrix, a stepped aggregate layer, a stepped high-strength foamed concrete layer, and a culvert. A main drainage pipe is inclinedly arranged in the aggregate layer, and lateral drainage pipes are provided on both sides of the roadbed slopes to drain moisture from the roadbed. The high-strength foamed concrete layer is laid above and on both sides of the culvert, providing good thermal insulation to address freezing issues exacerbated by wind tunnel effects, and buffering the frost heave force of the surrounding soil to prevent direct frost heave force from causing compression damage to the culvert structure. This structure forms a multi-level stiffness transition from flexible to semi-rigid along the culvert transition section of the roadbed, reducing differential settlement and misalignment risks at the connection between the culvert and the roadbed, improving the overall stability of the roadbed and driving safety. The overall structure is reliable, easy to construct, and suitable for widespread application in cold regions.

This invention relates to the field of circulating water treatment equipment technology, specifically to an integrated physical descaling and filtration device for circulating water in district cooling and heating systems. The device includes a treatment tank, an inlet pipe and an outlet connected to the treatment tank, and a filter screen disposed within the treatment tank. The inlet pipe is arranged tangentially to the treatment tank to allow circulating water to enter tangentially and form a vortex. The outlet is located at the top of the treatment tank to discharge filtered circulating water. The filter screen is disposed below the outlet to filter the circulating water. This invention uses a tangential inlet pipe to create a vortex within the treatment tank, utilizing centrifugal force to separate impurities. The filter screen employs an elastic suspension structure, combined with a hydraulically driven impact mechanism and a rotating scraper, to achieve simultaneous cleaning of the inner and outer walls, effectively preventing scale bridging and clogging. Its modular design facilitates maintenance and offers the advantages of high efficiency, energy saving, and no need for external power.
